Jaswinder Singh Rajput c3043569dc perf stat: Micro-optimize the code: memcpy is only required if no event is selected and !null_run ...

Set attrs and nr_counters if no event is selected and !null_run.

Setting of attrs should depend on number of counters,
so we need to memcpy only for sizeof(default_attrs)

Also set nr_counters as ARRAY_SIZE(default_attrs) in place of
hardcoded value.
